Figure 3

The bird's-eye view of SEM images of the samples subjected to electrodepositions under the current density of (a) 2 mA/cm 2 for 40 min and (b) 1 mA/cm 2 for 80 min, respectively, and (c) the sample immersed in the plating solution without applied potential. The diameters, the lengths, and the inter-wire distances between nanowires of samples used in (a) and (b) were identical.
